Features

Easergy MiCOM P740 is one of the fastest and complete in its class, providing secure and sensitive protection for all types of voltage busbar configurations. It is easily adapted to any configuration and can operate with different types of CT.

Fast, adaptable and easy to maintainTypically operating at 11-15ms, Easergy MiCOM P740 enables fast fault trips. It can be adapted to any busbar configuration and operates with different types of CT. A high-speed fiber optic cable, which eliminates insulation-related problems, can be used for communications between the Central Unit and the Peripheral Units.

Fully communicantWith the availability of IEC61850-8-1 and IEC103 protocols, the Easergy MiCOM P740 is easily integrated in any substation system.

Latest communication protocols & Ethernet Redundancy (available now in P741)Fully Equipped with the latest communications protocols (IEC61850 Ed1 & Ed2 available in the same device, selection by setting).Maximum availability and reliability of Ethernet communications thanks to the implementation of PRP/HSR standard redundancy protocols with an instantaneous recovery time (0 ms) in case of network failure.Dual IP address allows the device to be connected to 2 independent communication networks (e.g, SCADA system network & Maintenance network)Universal IRIG-B input (automatically detects modulated or unmodulated signal)

Major enhancement to Cybersecurity (available soon, please contact your local representative for model availability)Operational & Cyber Security, compliant to IEC 62351, helps protect installations with security based on embedded features such as Role Based Access Control (RBAC), Port Hardening, Security Logs and Access Traceability. The IED by default includes RBAC with different users defined and a Security Administrator.

Applications

The Easergy MiCOM P740 numerical busbar protection scheme has been designed to protect a wide range of busbar configurations. The modular scheme utilises 2 types of device:

Central Unit (CU) - P741

Peripheral Unit (PU) - P742 or P743 dependent on scheme

The units interconnect using fibre optic cables and together with the topology configurator software, allow application to all types of busbar configurations. The Central Unit co-ordinates the scheme, receiving signals from all the peripheral units associated with the protected busbars and acting on these signals, initiates a bus zone protection trip when necessary.
